Answer:
Step-by-step explanation:
Yes; In every column the ratio cost to weight is equivalent to the unit rate of $3.50 per pound.
To solve this problem you must follow the proccedure shown below:
1. You have the following information given in the problem above:
- <span>Marta is making 3 servings of fruit salad.
- Marta adds 3/8 cups blueberries for each serving.
- Her measuring cup holds 1/8 cup.
2. Then, you have:
1 time----1/8 cup
x----3/8 cups
x=(3/8)/(1/8)
x= 3x8/1x8
x=24/8
x=3 times
H</span><span>ow many times must Marta measure 1/8 cup of blueberry to have enough for the fruit salad?
The answer is: 3 times</span>
<span>In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
The shorter leg is </span>the side opposite the 30 degree angle, therefore
the shorter leg = 30/2 = 15
<span>By the Pythagorean theorem
</span><span>the longer leg = </span>√(30² - 15²) = √(900-225) = √675 = 15√3 ≈ 25.98 units
Given :
Length of one of the equal sides of an isosceles triangle = 3x+2
Then, length of the other equal side will also be = 3x+2
Length of the unequal side of this isosceles triangle = 14
Formula for finding the perimeter of an isosceles triangle :
A formula for finding the perimeter of this isosceles triangle :
Bringing all like terms together we get :
Thus, the formula = 6x+18
Therefore, a formula to find the perimeter of this isosceles triangle = <u>6x+18</u>
